Pressure Plates not turning off!

USING STONE PLATES!!!

I was making a capture the flag map and I was testing it out, and then one of the pressure plates refused to turn off! It was stone. as soon as you step on the pressure plate, it triggers teleporting command blocks.

What I expected to happen:

1. I teleport on to a pressure plate.
2. pressure plate instantly teleports me away (using command blocks)
3. pressure plate turns off

What really happened

1. I teleport on to a pressure plate.
2. pressure plate instantly teleports me away (using command blocks)
3. pressure plate stays on and ruins the entire thing.
